Answer:
2
Step-by-step explanation:
substitute n=1 and n=3 in the given equation
1 st term is (1)^2-1-2 = 1 -1 -2 = -2
3rd term is (3)^2-3-2 = 9-3-2=4
sum of 1st and 3rd term is -2 + 4 = 2
120-36 = 84 <==== what he has left
84/120×100% = percentage of what he has left
70% = percentage aka answer.
13 to the second power is 169.
Hope this helps!
